Abstract

A connector including a body, an adjacent pair of first terminals, a second terminal next to one of the first terminals, a third terminal next to the other first terminal, and a fourth terminal. The body holds the terminals at least partially and includes a first recess, a second recess, and a first separating portion therebetween. The first and third terminals each have a portion exposed through the first recess. The fourth terminal has a portion exposed through the second recess. The second terminal includes an exposed portion and an unexposed portion. The unexposed portion includes an area on one side in the first direction of a part in the second direction of the second terminal and is covered with the body. The exposed portion includes an area on the other side in the first direction of the part of the second terminal and is exposed through the first recess.

First claim

The invention claimed is:

1. An electrical connector, comprising:
terminals, wherein the terminals include a pair of first terminals, a second terminal, a third terminal, and a fourth terminal spaced from each other along a first direction, the first direction being an arraying direction of the first, second, third, and fourth terminals, the first terminals being differential signal terminals being elongated in a second direction and adjacent to each other in the first direction, the second direction crossing the first direction, the second terminal being a ground terminal elongated in the second direction or a low-speed signal terminal elongated in the second direction to transmit a signal at a lower speed than the first terminals, the second terminal being located next to one of the first terminals on one side in the first direction, the third terminal being a ground terminal elongated in the second direction or a low-speed signal terminal elongated in the second direction to transmit a signal at a lower speed than the first terminals, the third terminal being located next to the other first terminal on the other side in the first direction, the fourth terminal being elongated in the second direction and located on the one side in the first direction relative to the second terminal; and
a body of an insulating plastic material, the body holding the arrayed first, second, third, and fourth terminals at least partially and including a first recess, a second recess, a first separating portion, and a first face on one side in a third direction, the third direction being a thickness direction of the body and crossing the first direction and the second direction, wherein
the first recess opens through the first face of the body and crosses the first terminals,
the second recess opens through the first face of the body,
the first separating portion is located between the first recess and the second recess,
the first terminals each include a first exposed portion,
the first exposed portion of each first terminal is a portion in the second direction of the first terminal, extends from one end to the other end in the first direction of the first terminal, and is exposed to an outside of the body through the first recess thereof,
the second terminal includes a first part that is a portion in the second direction of the second terminal and that extends from one end to the other end in the first direction of the second terminal,
the first part of the second terminal includes a first unexposed portion and a first exposed portion,
the first unexposed portion of the second terminal is an area on one side in the first direction of the first part of the second terminal and is covered with the body so as not to be exposed out of the body,
the first exposed portion of the second terminal is an area on the other side in the first direction of the first part of the second terminal and is exposed to the outside of the body through the first recess thereof,
the third terminal includes a first part that is a portion in the second direction of the third terminal and that extends from one end to the other end in the first direction of the third terminal,
the first part of the third terminal includes a first exposed portion,
the first exposed portion of the third terminal includes at least an area on one side in the first direction of the first part of the third terminal and is exposed to the outside of the body through the first recess thereof,
the fourth terminal includes a first part that is a portion in the second direction of the fourth terminal and that extends from one end to the other end in the first direction of the fourth terminal,
the first part of the fourth terminal includes a first exposed portion,
the first exposed portion of the fourth terminal includes an entire or partial area in the first direction of the first part of the fourth terminal and is exposed to the outside of the body through the second recess thereof.

2. The electrical connector according to claim 1 , wherein
the second recess is provided on one side in the second direction relative to and in spaced relation to the first recess of the body.

3. The electrical connector according to claim 2 , wherein
the second terminal further includes a second part being another portion in the second direction of the second terminal, the second part being located on the one side in the second direction relative to the first part of the second terminal,
the second part of the second terminal extends from the one end to the other end in the first direction of the second terminal and includes a second exposed portion, and
the second exposed portion includes at least an area of the second part of the second terminal, and the second exposed portion is exposed to the outside of the body through the second recess thereof.

4. The electrical connector according to claim 1 , wherein
the body further includes a first thickness portion, a second thickness portion, and a second face on the other side in the third direction,
the first thickness portion is a portion of the body on one side of the third direction relative to the first, second, and third terminals,
the second thickness portion is a portion of the body on another side of the third direction relative to the first, second, and third terminals,
the first recess comprises top and bottom first recesses,
the top first recess passes through the first thickness portion of the body, from the first, second, and third terminals to the first face of the body, and
the bottom first recess passes through the second thickness portion of the body, from the first, second, and third terminals to the second face of the body.

5. The electrical connector according to claim 4 , wherein
the body further includes a third thickness portion and a fourth thickness portion,
the third thickness portion is a portion of the body on one side of the third direction relative to the fourth terminal,
the fourth thickness portion is a portion of the body on another side of the third direction relative to the fourth terminal,
the second recess comprises top and bottom second recesses,
the top second recess passes through the third thickness portion of the body, from the fourth terminal to the first face of the body, and the bottom second recess passes through the fourth thickness portion of the body, from the fourth terminal to the second face of the body,
the first separating portion comprises top and bottom first separating portions, and
the top first separating portion is located between the top first recess and the top second recess, and the bottom first separating portion is located between the bottom first recess and the bottom second recess.

6. The electrical connector according to claim 4 , wherein
the body further comprises:
a third recess opening to the first face of the body and extending in a direction including a component of the first direction, and
